Questions fréquentes
Which SQL dialects are supported?
Standard ANSI plus dialect-specific keywords from MySQL, PostgreSQL, SQL Server, SQLite, and BigQuery. Rare vendor extensions may not indent perfectly.
Does it validate my SQL?
No. It only reformats - a syntax error in your SQL will still appear in the output. Use your database's EXPLAIN for validation.
Are comments preserved?
Yes. Both -- line comments and /* block comments */ are kept in place.
Is my query uploaded?
No. Formatting runs entirely in your browser.
